    May I ask where you are getting the Pinacryptol Yellow for your FX-2? I've not been able to find any recently...

    Uuh, what does Pt./Pd mean? POP?

    Randy, a guy here in Finland makes this Pyrocat HD and FX2. I just do not know if he sells abroad. www.hopeavedos.fi (I'm afraid the site is only in Finnish). It's the second link "Kehitteet".

    Platinum (Pt), Palladium (Pd), Printing out paper (POP)

    They are historic, or 'Alternative', printing processes.

    I don't use Pinacryptol Yellow in my FX-2.

    Here is the recipe for Crawley’s FX-2:

    I've read that, but I never use that type of film so I was concerned about how much fog would occur. Have you compared the difference between the full formula and that without the Pinacryptol with a film like Pan F+ or FP4+? I'd be interested to see how much is 'slightly'.

    Randy, I don't have densitometry for Pan F+ or FP 4+ developed in FX-2. For Efke 25 and Efke 100 developed in FX-2 with no Pincriptol Yellow, Visual Channel Base+Fog was .16 and .17 respectively.

    Thus is about what I get for Base+Fog for the same emulsion numbers of Efke 25 and Efke 100 developed in Pyrocat - MC. (which I regard as a low fog developer).

    Cool, thanks. I'll have to mix up some fresh without and give it a shot. Thanks for the info.

    A good starting place for converting from regular agitation ot semi stand is... double the time. With Xtol, Rodinal, and many others, it works quite well.

    My version of semi stand is agitation every 5th minute, for 15 seconds. It keeps most of all the benefits of standing development ( tonality, acutance, etc. ) while minimizing potential problems like uneven development or streaking.

    I know this is pretty general, but a start is a start.

    and those with any imagination and understanding are filled with doubt and indecision"

    OK, here is the data I have for a couple of the films you ask about. This is based on a dilution of Pyrocat-HD of 1:1:150 for semi-stand. That is, initial agitation for 1.5 minutes, and them once again for ten seconds at the 1/2 point of total development time.

    FP4+
    high contrast scenes, 25 minutes
    medium contrast scenes, 35 minutes
    low contrast scenes, 50 minutes

    HP5+
    high contrast scenes, 40 minutes
    normal contrast scenes, 50 minutes
    low contrast scenes, 65 minutes

    Times for TRI-X 400 should be very close to those for HP5+, but I have not tested this. I don't have anything for the other films.
